DS1816-20/T&R

Supervisors Overview

The DS1816-20/T&R is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It functions as a power supply support circuit with a fixed threshold voltage of 4.62 V, designed to monitor a single input channel. The device features an active low, open drain output type and includes manual reset capability. It operates within a temperature range of -40°C to +85°C and supports a maximum supply voltage of 5.5 V. The component utilizes a TO-92-3 through-hole package and is supplied in tape and reel format.

Supervisors Feature Summary

• Provides fixed voltage supervision for single-channel power systems
• Features open drain output configuration for flexible interfacing
• Includes manual reset functionality for system control

Supervisors Applications

• Power supply monitoring in embedded systems
• Voltage supervision for microcontroller circuits
• System reset generation in industrial equipment

Supervisors Procurement Notes

Verify the specific manufacturer source, as Analog Devices acquired Maxim Integrated. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary. Ensure the TO-92-3 through-hole package matches your PCB design requirements before ordering.

Supervisors Selection Notes

Select this component when a fixed 4.62 V threshold is required for power monitoring. Consider the through-hole TO-92-3 package if surface-mount options are unsuitable. Verify that the open drain output aligns with your system's logic levels and reset circuitry requirements.

Supervisors Part Context

This part belongs to the DS1816 series of EconoReset supervisory circuits. It is distinct from other variants like the DS1816R-20-U+ which uses a SOT-23-3 package. The series is designed for cost-effective power management solutions requiring reliable voltage monitoring and reset generation.

Supervisors Replacement Considerations

Check for direct substitutes within the DS1816 family with different packages or thresholds. Verify compatibility with alternative voltage supervisors offering similar open drain outputs and manual reset features.
